Let the hive mind of Engadget get that for you.
"I'm looking for a solid state drive, around 32 to 64GB, for use in my web server. The drive will contain my web sites and the operating system, either Windows Server 2008 R2 or Ubuntu. Large storage is handled by a separate RAID array, so capacity is not an issue. Rather, I am looking for the fastest, longest-lasting, and most reliable drive under $150 that is suitable to my application. Any thoughts? Thanks!"
I would like to see Apple come out with a 32GB Apple TV for the car. If it were flash-based, it could be much smaller. Someone suggested a 32GB iPod touch, but the beauty of the Apple TV is that it would automatically synch when I pull into my driveway. Not being hard drive-based would be best in a hot (and bumpy) environment like a car.
